EVAPORATOROR SIRUP-PAN.

SPECIFICATION forming part of Letters Patent No. 445,266, dated January 27, 1891.

Application filed May 27,1890. Serial No. 353,312. (No model.)

To all whom t iii/Cty concern:

Be it known that I, GEORGE W. RoDGERs, a citizen of the United States, residiugat Lisbon, in the parish of Claiborne and State of Louisiana, have invented a new and useful Evaporator or Sirup-Pan, of which the following is a specification.

This invention has relation to improvements in evaporator or sirup-pans` and among the objects in vieware to provide a pan so constructed as to effect a saving of the sirup, which is self-skimming, and which will avoid any scorching of the sirup or juice during evaporation.

Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure l is a perspective of an evaporating or sirup pan constructed in accordance with my invention. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section through the rear end bar.

Like numerals of reference indicate like parts in all the figures.

In constructing my pan I employ the usual longitudinal side bars l, arranged parallel to each other and connected near their ends by end or transverse bars 2, let into the side bars, which side bars are continued for a short distance beyond the end bars and reduced to form handles 3, whereby the pan may be conveniently carried. To the frame thus constructed is secured the sheet-metal bottom plate 4, by screws or otherwise, which securin g devices take into the under edges of the side and end bars.

The space within the pau is divided into a series of compartments, in this instance five, and designated as 5, 7, 8, and 9, which compartments are formed by a series of transverse partitions l0. The partitions l0 are graded as to depth, the first partition being very narrow and extending but a slight distance above the bottom of the pan, the second slightly deeper, and the third still deeper, and so on throughout the series. lVith the exception of the narrowest partition, there is mounted in front of each a pair of guideblocks ll, and between the partitions and the guide-blocks are located vertically-sliding gates l2, adapted to regulate the width of the slots or passages. The upper edge of each partition at its opposite ends is beveled or cutaway, as at 13, so that its ends are lower than the central portion of the partition, and the lower edge is transversely recessed, as at ll, to form communicating passages. The rear end bar 2 is provided at its center with a drainage-port 14:, which port passes through the end bar and parallel with the same and through one ot' the side bars.

The raw sirup is first poured into the compartment 9 and passes from the same through the passage 14 into the next compartment 8, and sc on from one compartment to the other until the last compartment is reached, by which time the juice has been reduced to a thick sirup, which passes out slowly through the discharge-port in the end bar Q. The dischargeport being in the center of the end bar the drainage from the last compartment is central and even and unlike the drainage heretofore employed, which took place through a side port or opening, and therefore drained at one side of the pan more rapidly than at the other, so that the sirup at the latter side was retained over the fire longer than the sirup at the drain side and thereby was liable to become burned.

The skimmings that rise from the sirup as it is evaporated overflow the edges of the several partitions at the sides of the same and iiow from one compartment rearwardly to the other until they reach the first compartment 9, in which the raw juice is introduced and from which the skimmings may be removed with facility and very little waste.

Having described my invention, what l claim isl. The herein-described evaporating-pau, the same consisting of a rectangular frame having a bottom and a series of transverse partitions,forming a series of compartments, and provided with openings in their lower edges to afford communication between the compartments, the rear end bar of the frame being provided with a draw-olf passage leading from one end of the said bar to about the center thereof and communicating with the end compartment of the series at that point, substantially as specified.
